Hi, new to this site, I have a 2.0 DOHC galaxy that has failed emmisions, i have changed lambda, cat,air flow meter ££££ ouch. Car runs fine but is over fueling, I have a p1132 and have been getting a p230 diagnostic code, lambda constantly running at 0.9 volts. Air pump works fine. Car will now not start. Fuel pressure regulator? Crank senser? I would be greatful of any ideas.Thanks
